When a gearbox, pump or motor shaft starts weeping oil, the fix usually comes down to one small component: the radial shaft seal. The DBH 9436 is a lip seal sized for a 56 mm shaft, an 88 mm housing bore and an 8 mm height, a combination that shows up often in power transmission and rotating equipment. Its Lx design pairs a sealing lip with a reinforced body for oil or grease service.

The code to remember is 9436, a radial shaft seal from the DBH line. Reading the size is straightforward: shaft 56 mm, housing 88 mm, width 8 mm. The Lx designation tells you the seal has a sealing lip plus a reinforced body, so it presses into a cylindrical bore and holds its shape in service. Once you have either the part number or the three measurements, finding the right item in the series is quick.

Seals in this size range are common in gearboxes, reducers, centrifugal pumps, electric motors and other transmission equipment. Their job is twofold: keep lubricant where it belongs and keep dust, water and particles out. You will also find them on fan, mixer and conveyor shafts, where a seal that holds up under continuous running helps bearings last and keeps unplanned downtime down.

Selection comes down to three checks: shaft diameter, housing diameter and the height you have to work with. Fit the seal on a clean shaft free of burrs, lubricate the lip first, and drive it in with a proper driver or support tube so it enters square to the shaft and the lip is not damaged. On equipment that sees heavy vibration or elevated temperature, look at the lip material and spring type before committing.

For an equivalent, the fastest route is to send the code 9436 or the measurements off the old seal: shaft, outer diameter and height. From there we can search the same family or propose a compatible replacement. We can also help when the housing has a shoulder or the shaft shows wear, so the sealing solution you pick actually fits the condition of the equipment.
